PRESERVING FARINACEOUS PRODUCTS.

SPECIFICATION forming part of Letters Patent No. 338.962, dated September 4, 1888.

Application filed January 15, 1886. Serial No. 188,664.

To all whom it may concern:

Be it known that I, 'lnorms TRUEMAN GAFF, a citizen ofthe United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in the Art of Preserving Furinaceous Products in the Dry State; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

According to my invention ordinary farinaceons products are inclosed in what I term a germ-tight bag, box, or wrapper, and thus inclosed are subjected to a sufficiently high temperature for such a length of time as will suffice to sterilize or deprive of life any germs or eggs or living foreign matter which may have been inelosed with such product in said germ-tight package, whether mixed with such p rod nctbeinga part ofsuch product-or contained in the inclosed air. By ager1n-tight package is meant a covering suitably applied which will exclude gerrnsof whatever kind or nature, although not necessarily airlight or gas-tight. One such material is good Manila paper, which I have successfully used as a wrapper in the preservation of the product from corn, known in the market as cerealinc, descrihcd in several United States patenls granted to Joseph Gent, the first of which patents is numbered 223,847. In preserving cercnline the following method was adopted and proved entirely successful: The cerealine was put in an ordinary paper box. A wrapper of good Manila paper was then posted on, so as to entirely cover and seal the paper box.

Thus wrapped, the package was lSpecimcns.l

put in a steam nlufile and subjected for about one hour to a temperatureof from 213 Fahreno heit to 215 Fahrenheit. On removal from the steam-motile a paper label completely covering the germ-tight Hanila wrapper was pasted on.

I do not confine myself to any particular 5 temperature, because that may be greatly varied, according to the nature of the product to be preserved and lhe character of the germtight covering. If a higher temperature is employed, the goods are exposed to it for a shorter period. Nor do I confine myself to any particular device for heating packages of farinaceous products for the purpose mentioned, although I recommend the use of a steainmufi'lc as most convenient. Nor do I confine myself to any particular mode of applying germ-tight coverings, or to any particular number of such coverings, one or more being applied, as may be deemed expedient-or required bythecharacterofthesaid covering.

I claim as my invention The art of preserving Iarinaccous products in a dry state, which consists in inclosing such products in pcrvious coverings of paper or fabric, and exposing them so inclosed to a baking temperature sufficientto sterilize or deprive of life germs, eggs, or living foreign mat ter within such covering and retaining the products so inolosed, substantially as described.

In testimony whereof I this my signature in presence of two witnesses.

THOMAS 'lRUEMAN GAFF.
